Abstract

Det er beskrevet en anordning og en korresponderende fremgangsmåte for å produsere et kontinuerlig skummet ekstmdatprodukt, hvori ekstruderingen og initiell ekspansjon av det skummede ekstmdatet blir utført inne i et kammer under delvis vakuum. Det skummede ekstmdatet (110) blir så fjemet fra kammeret (102) gjermom en åpning (106) som er nedsenket irme i en væskeskjerm (108a), (108b). Dimensjonene til det skummede ekstmdatet blir overvåket mens det nærmer seg åpningen, og om nødvendig, blir den effektive dimensjoneringen av åpningen justert ved bevegelsen av et par av sideporter (124) og en enkelt vertikal port (132) anordnet ekstemt for åpningen for å tilpasse åpningen til det skummede ekstmdatet og forhindre sttømmen av væske irm i kammeret gjermom åpningen.
